What modifications might this car have?
 

Deni,

his name is amg250. Try to ask him.

I asked him in the comments, to which he replied that he set the boost to 1.5 bar and rev limiter to 5200 rpm. I replied back that those 2 "modifications" will not give the car at least 200 hp (judging by the 0-100 kph time). He then replied back that it's a secret :(.

Where is he from?
AMGs have better Turbos and maybe further mods, in case it is a real AMG
If he did it well, he should have 7 mm elements and IC.
As long as we don't see the engine (is it the original 5 cyl) I won't believe anything.
And on top, people with too many secrets...
